In a power-supply control device, power supply to loads is controlled by driving circuits separately switching on or off FETs, respectively. In a state in which the connection destination of a fuse element is the FET, a microcomputer provides an instruction to switch the FET off. Then, the microcomputer determines whether or not a current is flowing through the FET. Upon determining that a current is flowing through the FET, the microcomputer switches the connection destination of the fuse element to the FETs, and provides an instruction to switch the FET on.
